Overview

Single row needle roller bearing with machined rings, with flanges

Single row needle roller bearings incorporate cylindrical rollers that are small in diameter relative to their length. Owing to their large number of rollers, the bearings have a high load carrying capacity. The outer ring includes two integral flanges to guide the bearing axially and an annular groove with one or more lubrication holes to facilitate relubrication.

Key features

High radial load carrying capacity
High stiffness
Low cross-sectional height
Accommodate axial displacement in both directions
Separable design

Typical applications

Automotive transmissions
Industrial gearboxes
Compressors and pumps
Links, pivots, and rocker arms

Selection guidance

Check mounting envelope, inner ring requirement, shaft surface hardness, lubrication, load, and speed range.
